New York City police officers tackled and took away for questioning a "suspicious man" outside Ground Zero today, where President Obama was leading a wreath-laying ceremony. The man was walking his bike towards the World Trade Center area and saying, "Secret Service, Secret Service coming through," after which cops tackled him and searched through his messenger bag. And according to the New Jersey Star-Ledger, "witnesses say may have pulled a gun out of a backpack as President Barack Obama's motorcade passed."
The cops found no gun in their search, though, and the man has since been released. If he was pretending to be a Secret Service member in order to cut through crowds, that probably wasn't the wisest decision.
